6 min de lectureMis à jour saison 2025–2026

The Marble Caves, known in Spanish as Capillas de Mármol (Marble Chapels), are a geological wonder carved by thousands of years of wave action into a marble peninsula on Lago General Carrera. The caves, tunnels, and arches display mesmerizing patterns of swirling blue, white, and grey marble, reflected in the turquoise glacial waters below.

Autumn, from mars through mai, offers what many consider the optimal visiting conditions. The sometimes fierce summer winds on Lago General Carrera tend to diminish en automne mornings, creating calmer water that allows boats and kayaks to venture deeper into the marble formations. The reflected colors are more vivid on still water, and the overall experience feels more immersive without the summer crowds.

The caves are accessed exclusively by boat or kayak from the small town of Puerto Río Tranquilo on the Carretera Austral. Several operators run tours ranging from small motorboats to guided kayak expeditions. En automne, groups are smaller — sometimes just a handful of visitors — allowing for a more personal experience with greater flexibility to linger at the most beautiful formations.

mars is the most reliable month, with mild weather, operating tours, and good water conditions. avril remains viable for visits, though tours may run less frequently. By mai, some operators close for the season, but those that remain offer the most exclusive experience of the caves. The turquoise water color, caused by glacial flour, persists toute l'année, meaning the visual spectacle is not diminished by the season change.

The marble peninsula also hosts the Cathedral (a large cavern), the Chapel (a smaller enclosed cave), and numerous arches and tunnels, each displaying unique patterns where water has sculpted the soft marble over millennia.
